About this service
Residential Plumbing in the Niagara Region
Your home's plumbing should be the last thing on your mind. When something goes sideways — a slow drain, a dripping tap, a mystery leak behind a wall — you want a real local plumber who shows up when they said they would, explains what's actually wrong in plain English, and fixes it right the first time. That's the entire reason Ottr Plumr exists.
We handle every residential plumbing job across the Niagara Region: from a single faucet swap on a Saturday morning to a full re-pipe during a basement renovation. Every job, big or small, gets the same treatment — shoes off at the door, drop cloths down, tools tidy, the work explained as we go, and the mess cleaned up before we leave. You'll know what we did, why we did it, and what to watch for going forward.
Our crew lives in Niagara. We know the housing stock — from century homes in St. Catharines and Niagara-on-the-Lake to post-war bungalows in Welland and Port Colborne to brand-new builds in Grimsby and Lincoln. That matters. A galvanized steel supply line in a 1940s home asks for a different game plan than a PEX manifold in a 2022 build, and we bring the right experience to both.
Most importantly: we quote before we work. Diagnostics first, then a clear flat-rate price, then your decision. No surprise pricing, no hidden line items added at the end. And if we open a wall and find something genuinely unexpected, we stop, show you, and give you a fresh quote before we touch it — you stay in control of every dollar.
What we do
Specialties under Residential Plumbing
Leak Detection
Acoustic and thermal locating to track down hidden leaks behind walls, under slabs, and in ceilings — before they ruin drywall, flooring, or insulation.
Fixture Installation
Faucets, toilets, sinks, tubs, garbage disposals, bidet seats — installed clean, level, leak-free, and to manufacturer spec so warranties stay valid.
Re-Pipes & Renovations
Full or partial repipes in copper or PEX, plus rough-ins and finals for kitchen, bathroom, basement, and addition projects.
Water Line Service
Main water line repair and replacement — including from-the-curb work and coordination with municipal locates.
Water Quality
Whole-home filtration, softeners, and reverse-osmosis under-sink systems to handle Niagara's hard water and tannins.

Common questions
Residential Plumbing FAQs
How quickly can you come out for a residential plumbing issue?
For most residential calls in the Niagara Region we offer same-day or next-day service. For active leaks, no-water situations, or sewage backups, call us at 289-488-1007 and we'll dispatch as fast as possible — we run 24/7 emergency rotation.
Do you give quotes before starting work?
Always. We diagnose the issue, walk you through your options (often with a quick repair vs. replace breakdown), and provide a flat-rate quote in writing before any work begins. You authorize, then we work.
Do you handle bathroom and kitchen renovations?
Yes. We do rough-in plumbing for renovations as well as final fixture installs — and we coordinate cleanly with your contractor, designer, or tile setter so the schedule doesn't fall apart waiting on the plumber.
What's the most common cause of slow drains in Niagara homes?
In older neighbourhoods, tree-root intrusion in clay sewer laterals is the #1 culprit. In newer builds it's almost always grease, hair, or so-called 'flushable' wipes (they aren't). A camera inspection tells us which one in about 20 minutes.
Can you repair frozen or burst pipes?
Yes — we thaw, repair, and reroute frozen and burst lines, and we'll show you why it happened (uninsulated rim joist, exterior wall plumbing, drafty crawlspace) so it doesn't happen next winter.
